The association of Campbell's song with the tune "Captain O'Kane" was made in R. A. Smith's 'The Irish Minstrel', 1825, according to Andrew Kuntz 'Fiddler's Companion Tune Index' on the Ceolas website. The basis for attribution to O'Carolan is also given there. The copy of the tune published by McGlashan is earlier than any copy in that index or in 'Sources of Irish Traditional Music', 1998.
